Functions
esp_err_t	display_oled_init (spi_device_handle_t spi)
	Reset the panel and run the SSD1333 init sequence (gamma, contrast, display on).
esp_err_t	display_oled_draw (const uint8_t *buf, size_t len)
	Blit a full framebuffer to the panel.
esp_err_t	display_oled_set_brightness (uint8_t level)
	Set the global panel brightness (SSD1333 Master Current, cmd 0xC7).
esp_err_t	display_oled_sleep (void)
	Put the panel to sleep (SSD1333 Display OFF, cmd 0xAE).
esp_err_t	display_oled_wake (void)
	Wake the panel from sleep (SSD1333 Display ON, cmd 0xAF).
esp_err_t	display_oled_clear (void)
	Clear the panel to black directly, without a framebuffer.
